Hello Neels Hofmeyr, Harald Welte,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/2465
to look at the new patch set (#6).
Introduce artifacts holding dependencies to speed up builds.
Basically, osmo-build.sh holds logic to check whether the necessary
artifact is available. If so it fetches artifact, unpacks it and
triggers the actual build. In case the necessary artifact is not
available osmo-build.sh simply builds all dependencies from source
by using osmo-build-dep.sh and archives deps to the ARTIFACT_STORE
afterwards.
The necessary functions to determine the artifact name from remote and
local repositories as well as the handling of artifact files live in
osmo-artifacts.sh, which is sourced by osmo-build.sh.
osmo-build.sh will be sourced by the contrib/jenkins.sh build script
inside each git repository and invoked via 'build'.
See jenkins-openBsc.sh [1] for more details.
Artifacts will be stored as follows:
$ARTIFACT_STORE/$JOB_NAME/<dep_1>.<branch_1>.<rev_1>_...
..._<dep_n>.<branch_n>.<rev_n>.tar.gz
Furthermore, ARTIFACT_STORE environment variable has to be set on all
jenkins slaves. The JOB_NAME variables is injected to each jenkins job
by jenkins.

+#!/bin/bash
+#
+# This script enables artifacts holding dependencies on a jenkins job level to
+# speed up builds. Basically, it holds logic to check whether the necessary
artifact
+# is available. If so it fetches artifact, unpacks it and triggers the actual
build.
+#
+# Otherwise it simply builds all dependencies from source by using
osmo-build-dep.sh
+# and archives deps to the ARTIFACT_STORE afterwards. Revisions of locally
built
+# dependencies are detrmined after dependencies are built to ensure catching
new
+# changes in dep_n+1 meanwhile dep_n building.
+#
+# Artifacts will be stored as follows:
+# $ARTIFACT_STORE/$JOB_NAME/<dep_1>.<branch_1>.<rev_1>_...
+# ..._<dep_n>.<branch_n>.<rev_n>.tar.gz
+#
+# In order to make use of osmo-build.sh one needs to source it, e.g. from
+# ./contrib/jenkins.sh. Furthermore you need to declare following functions
+# within a build script that sources osmo-build.sh:
+#
+# - genericDeps()
+# - buildProject()
+#
+# More information about those function are given in the following template:
+#
+# source osmo-build.sh
+#
+# genericDeps() {
+# # Specify dependencies in the following way:
+#
+# x="$($1 libosmocore master ac_cv_path_DOXYGEN=false)"
+# x="${x}_$(PARALLEL_MAKE=-j1 $1 libosmo-abis)"
+# x="${x}_$($1 libosmo-netif)"
+#
+# echo "${x}.tar.gz"
+#
+# # The following 'parameters' can be adjusted within the
genericDeps function:
+# #
+# # x="${x}_$(<PARALLEL_MAKE> $1 <DEPENDENCY/REPO>
<BRANCH(default:master)> <CFG>"
+# #
+# # Furthermore, $1 represents the following script/functions:
+# # - osmo-build-dep.sh
+# # - getArtifactNameLocally() (osmo-build.sh)
+# # - getArtifactNameRemotely() (osmo-build.sh)
+# }
+#
+# buildProject() {
+# # Necessary commands to build the project, expecting all
dependencies have
+# # been build or fetched. Commands within buildProject() will be
executed
+# # in jenkins' $WORKSPACE per default.
+# }
+#
+# build
+#
+# Furthermore, ARTIFACT_STORE environment variable has to be set on all
jenkins slaves.
+# The JOB_NAME variables will be injected to each jenkins' job by jenkins
itself.
